On May 27, Umbra and Streamflow announced the launch of a private token vesting feature on Solana. The companies stated that this feature allows project teams to complete token vesting and distribution on a large scale while maintaining confidentiality. The solution is supported by Arcium's cryptographic execution engine, enabling Streamflow clients to continue using distribution mechanisms such as time locks and price triggers while concealing actual token transfer records. Recipients will receive vested tokens directly through the Umbra wallet, and each new vesting plan will further expand Umbra's shared anonymity pool, enhancing the privacy protection capabilities for users and applications across the entire network.
